Best Practices for Browser Management

Three Options to Ensure a Robust Experience for Users of PatientKeeper .0

PatientKeeper is a true thin client application. As a result, end user experience is a function of both PatientKeeper software and the browser within which PatientKeeper runs.

Browser technology has advanced significantly in the past five years and today’s modern browsers (IE9+, Chrome, and ) allow for a much richer user experience. In turn, PatientKeeper v8.0 incorporates new technology which takes advantage of these advances to significantly improve the user experience. At this point in time, this new technology is primarily employed by our charge capture application (to make the transition to the complexities of ICD-10 straightforward for physicians) and the new self-service patient list creation functionality. Other PatientKeeper applications rely less heavily on the new technology – although that will change in the future.

PatientKeeper has been able to ensure that our applications that leverage this new technology will still function in the five- to seven-year-old IE7 and IE8 browsers. However these browsers are inefficient when running modern applications. In fact, ’s applications no longer support IE8 as of Nov 15, 2012. Not surprisingly, PatientKeeper’s applications run more slowly on IE7/IE8 than on more modern browsers. The slower the machine’s processor and the less memory it has, the greater the performance penalty will be (see chart on page 3).

At this time, there are three options to ensure a robust experience for your users in PK v8.0:

1) Upgrade to IE9 or IE10 and run the browser in IE8 or IE7 compatibility mode for any applications or sites that require older browser technology. 2) Continue to run IE7 or IE8 and add the Frame plug-in. 3) Use an alternate browser (e.g. Chrome) to run the PatientKeeper application.

Note that it is not possible to upgrade past IE8 on PCs still running Windows XP so option #1 is not possible on these old machines. However, Windows XP itself will no longer be supported by after April 2014, so most organizations are in the process of upgrading these PCs.

The Path of Least Resistance

The Chrome Frame plug-in is likely the path of least resistance for most organizations. It can be installed either manually on individual PCs or pushed out to all PCs via Internet Explorer enterprise management. The plug-in is passive on the desktop and will not affect any application/website except those that are explicitly designated to use it.

Google will stop support of this plug-in in January 2014, mainly due to the decreasing use of IE8. However, the plug-in is open-source and will be supported by and available from PatientKeeper until it is no longer needed by our customers.

Chrome Frame Plug-In Information

1) Installing the plug-in does not install Chrome browser on the user’s computer. End users cannot use the plug-in to use Chrome to browse the web or access any web application.

2) Only applications or web pages that are specifically written to take advantage of the plug in will use it.

3) When a user opens an application or web page that is specifically written to take advantage of the plug in, it is almost impossible to tell that it is not running in IE8 (except of course that the page will load much faster). Trained users can tell by the slight differences in formatting/rendering of things like scroll bars in Chrome (scroll bars are slightly thinner in Chrome than in IE) or by opening task manager and observing that there is a Chrome process running.

4) The plug-in can be distributed using Group Policy Objects (GPO).

5) The MSI installer is available from Google’s website at http://www.google.com/chromeframe/eula.html?msi=true. There is also more information about the plug-in on this site.

6) For the plug-in to work, the IE setting “Enable Third-Party Browser Extensions” under Internet Options Advanced Panel must be enabled. This is enabled by default when installing IE7 or IE8.
